WHEEL-PLOW.

SPECIFICATION forming part of Letters Patent No. 319,440, dated June 9, 1885.

Application filed July 19, 1884.

T0 ctZZ whom it may concern:

Be it known that I, J OHN W. BARTLETT, of Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Wheel-Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in plows, the object of the same being to provide an improved beam and means for attaching the same to the plow, whereby the plow will be forced through the ground by the pressure of the end of the beam against the lower portion of the standard, a further object being to provide improved means for attaching the colter to the plow-beam and standard, whereby the colter is caused to rise and fall simultaneously with the plow-point, and independently of the motion of the beam.

With these ends in View, my invention consists in certain features of construction and combinations of parts, as will hereinafter be described, and pointed out in the claims.

In the accompanying drawings, Figure l is a View in side elevation of a portion of a wheel-plow embodying my invention. Fig. 2 isja modification.

A represents a plow-beam supported by the front wheel, a, rear furrow-wheel,a, and a landwheel. (Not shown.) The beam A forms the main portion of the frame-work to which the plow, colter, and operating mechanism are attached. The beam A is preferably of iron or steel in one piece, and curved downwardly and forwardly at the rear, as shown.

The plow B is pivotally secured to the beam A at the heel of its land side I), in the following manner: The beam is provided with an elongated closed slot, 0, located at that per tion of the beam which is the lowest, and at a distance back from the end of the plow-beam sufficient to allow the end of the beam to project forwardly into contact with the lower portion of the plow-standard D, or any other suitable stop located at or forward of the center of the plow when the said slot 0 is opposite the rear portion of the land side I). A belt or stud, I), set in the land side, passes (No model.)

through the slot 0, and by means of a nut, 12 looks the plow to the beam.

The plow-standard D embraces the sides of the beam and is connected by a link or arm, (I, pivotally secured in its upper end, with an operating lever, E. The plow by means of the elongated slot 0 is allowed a limited amount of longitudinal play on the beam. Thus when the plow is at work the end of the beam bears against the lower portion of the standard and the plow is forced through the ground by this pressure alone, the bolt 1) having no bearing against the front end of the slot 0; but when the plow. is thrown out of furrow the pressure of the beam against the lower portion of the standard is released and the plow is worked easily on the pivotal bolt b. Furthermore, the point of contact between the end of the beam and the standard or other suitable stop is at or forward of the center of resistance of the plow, and the plow for this reason runs steadily and is guided with ease, the point having no tendency to deflect to the right or left of the line of draft.

A colter, F, is journaled in the fork f, the latter being hinged to a depending lug or to depending lugs g, secured to or formed integral with a plate or clip, G, secured to the beam A, and by means of the hinge is allowed to oscillate in a vertical plane.

A rigid link, H, bifurcated at its ends for the purpose of straddling the colter and the beam, loosely embraces the colter-axle at the opposite end of the colter-hub and is connected at the other ends with the plow-standard by a connecting-rod or link, it. The latter may conveniently form an extension of the link (1 or it may be a separate link, or the link H may be connected directly with the standard. By this arrangement the movement of the operating-lever toward the rear will simultaneously lift the colter and plow-point while the forward motion of the lever will depress them, and by means of suitable devices for locking the lever in different positions a sector-bar, I, and spring-pressed dog, for example, as shown in Fig. 2, the plow-point and colter may be made to cut deeper or shallower, their relative depths of out remaining the same.

In Fig. 2 the colter-fork f embraces the,

ILA)

beam above instead of beneath, theolojeet be ing to .removethe lugs, to'which thehfork is pivoted, from interference with the attaching devices at the end of the beam.

I am aware that plows have been constructed to be drawn through the ground byabeam attached to the heel and to the standard and to the standard alone; but I am not aware that a plow pivotally attached to the beam at its heel has ever been constructed to be forced through the earth by the pressure of the end of the beam in loose contact with the standard or other suitable stop located near the foot of the standard.

It is evident that slight changes may be made in the form and construction of the several parts described without departing from thespirit and scope of my inventionas, for example, the slot 0. might be formed in the landside and the bolt 6 set in thebeam and 1 resting flush with the surface of the landside, and the colter-fork might be hinged to the side or sides of the beam; hence I do not wish to limit myself strictly to the construction herein set forth; but

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a curved beam, of a plow pivotally secured to the beam near its end, the end of the beam extending f0rward and forming a loose contact with the standard or other suitable stop, substantially as set forth. 2. In a wheel-plow, the combination, wit

- a beam curved downwardly and forwardly at the rear end, of a plow pivotally secured at its heel to the plow-beam, and having a forward and backward play on the pivotal bolt, whereby the end of the beam is caused to sus- -tainthe resistance of the plow when at work, substantially as set forth. a

3. In a wheel-plow, the combination, wan a plow-beam curved downwardly and forwardly at the rear end, and provided with a hori- 'zontaloblon'gslot located a short distance from its end, of-a plow pivotally secured to thebeamby a bolt at the heel of its landside,

. said bolt passing through the slotin the beam, whereby the end of the beam rests in contact with the lower portion of the standard, and takes the full resistance of the plow when at work, substantially as set forth.

l. In a wheel-plow, the combination, with a plow and a lever for adjusting the plow, of a colter secured to the plow-beam in a free Vertically-rocking motion, and a rod connecting the colter and operating-lever, whereby the plow and the colter are simultaneously adjusted to cut deeper or shallower, substantially as set forth.

5. In a wheel-plow, the combination, with a plow pivoted to the frame, and'a lever for rocking the plow on its pivot, of a colter secured to the plow beam or frame, in a free Vertically-rocking motion, and a rod or rods or a link connecting the colter-axle and plow-' operating lever, whereby the point of the plow and the colter are simultaneously elevated or depressed, substantially as set forth.

6. In a wheel-plow, the combination, with a plow pivoted at its heel to the beam, and a in a'free vertically-rocking motion, and devices connecting the eolter and the plow-stand ard, whereby the colter is elevated and depressed simultaneously with the plow-point, substantially as set forth.

7. In a-wheel-plow, the combination, with a plow and a lever for adjusting the plow, of a vertically-adjustable eolter secured to the plow beam or frame, and a rod connecting the colter and operating-lever, whereby the plow and colter are simultaneously adjusted to cut deeper or shallower, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
